Anyone have any opinion on a user friendly and low-to-mid-priced CWDM or DWDM system?

We need to take one pair of dark fiber and get about 5-6 10G ports on both sides.

This is the info that the DF provider has given us on the route:

Operating Wavelength: 1310/1550nm
Maximum Attenuation: 0.35 dB/km for 1310 wavelength
      0.25 dB/km for 1550 wavelength

Any suggestions would be tremendously helpful.

thanks,

This should fit the pricerange:

Haven't used them yet but know of one local operator that is using them and
is very satisfied...

We are using a couple of CUBO's passive DWDM muxes @ DE-CIX. Work like a
charm.

All our dwdm backbone is CubeOptics powered. We have about 30 pairs of DWDM band-spliiters and muxes.
The attenuation is the lowest we have seen on all the wdm muxes we have tested.

The tech guys @Cube optics are really smart. You can also ask for a specific mux if you have a want THE MUX.

You can buy CubeOptics muxes your eyes closed

+1 on the CUBO recommendation. In addition to muxes, we've worked
with them as a supplier of (Finisar) colored optics; our dealings have
been extremely favorable on all fronts.

what kind of 10G ports? 10gige? if so, i do not see how the cubo
stuff helps.

will http://xkl.com/ do it for you (if short range)?

Yes, sorry I should've specified 10Gig-E and I would like to avoid using CWDM/DWDM optics if possible I would just like to use regular LR optics.

The common misconception is that, just because you're not installing
colored optics directly in your router, something similar doesn't live
elsewhere in your system, mingled with a number of OEO conversions.
Neat packaging and pretty GUI is orthogonal to cheap, and you stated
both as initial requirements, so you're probably best choosing one or
the other. We may differ on levels of frugality, however I can't
think of any active system I'd classify as "cheap"; at the base,
you're looking at a 2x multiplier from something assembled with cubes,
however you slice it...

If you find yourself stuck with SFP+ interfaces, or partners who don't
grok this stuff and require a "conventional" LR hand-off, perhaps a
2xXFP transponder is really what you're after -- feed your mux with
the colored optics, and the other end with some LR (or SR, CX4, ...).
MRV has some good products in this space.
